ill!) I Patented Oct. 1, 1935 UNlTED STATES PATENT OFFICE Claims.

This invention has to do with improvements in window sash and the like. The improvements as herein disclosed have to do with features of construction which make it possible to swing the sash back into the room or interior of the building so that said sash can be conveniently reached on both of their faces, as for example, for the purpose of washing both faces of the glass panels, or for other purposes. In this connection it may be stated that the present invention relates to improvements in window sash of the general type disclosed in Letters Patent of the United States No. 1,877,631, issued September 13, 1932, but it will appear that certain of the features disclosed herein may also be used to advantage in connection with other forms of window sash than that type specifically disclosed in the aforesaid Letters Patent. Nevertheless, inasmuch as the present features are especially useful in connection with constructions of the general form disclosed in the said earlier Letters Patent I have chosen to illustrate the present features in a construction similar in some respects to that of the said earlier patent, but in so doing it will be understood that I do not intend to limit myself thereto, except as I may do so in the claims to be hereinafter made.

In the general type of window sash disclosed in the said earlier patent, provision is made for hinging each of the sash, upper and lower, at one edge thereof, by means of a sliding hinge or hinges located at one side edge of the sash, andsaid hinges are suitably supported so that as the sash is moved up and down the hinges travel 71 therewith; and provision is also made for counterbalancing each sash by means of counterbalancing weights or a weight located at and travel-- ling adjacent to the hinged edge of such sash. The arrangement of that patent is also such that one sash is hinged along on vertical edge thereof, and the other s h is hinged along on the other vertical edge thereof, so that when the sash are swung out into the room one swing-s one way and the other swings the other way and furthermore the counterbalancing weights-for the two sash do not interfere with each other due to the fact that they are located at opposite sides of the structure.

The general arrangement of that earlier patent is also such that each sash is intended to be swung out into the room when located at or near to the lower extreme of its sliding movement. For this purpose provision was made for moving or removing the lower portion of the trim strip at one side of the window casing op-- posite to the lower half of the casing, so that the inside or lower sash could be swung out into the room; it being found that the trim strip at the other side of the casing did not have to be moved or removed for such purpose nor for the 5 purpose of allowing the outer or upper sash to be swung out into the room when in its lowered position, since said sash stands outwardly away from the trim strip far enough to clear said strip due to the curvature on which said sash swings when turned on its hinges. It is, however, necessary to move or remove the parting strip which is located between the two sash when the upper sash is to be swung out into the room.

When the sash is supported solely from one upper corner, due to attachment of the counterbalancing cable thereto, it follows that thereis a tilting tendency due to the weight of the sash itself which tends to tilt the sash and cause it to bind in the casing, so that the freedom of movement and ease thereof is lessened.

It may be stated that objects of the present invention are to improve the construction and operation of the hinges by simplifying them and so forming them that the forces which they are called upon to carry will be better received from the sash and transmitted to the sliding supports whereby the hinges are carried by the casing; thus providing a more rugged and better structure, and one such that the sash will run easier both up and down; and in this connection to so arrange the hinges that they will better support the weight of the sash both when the sash is turned into its normal or working position and when it is swung out into the room: to provide rollers or the like for receiving and transmitting the twisting or tilting tendency of the sash due to support thereof only at one corner; such rollers being so placed that they can be easily reached for purposes of replacement or adjustment from time to time: to provide an improved form and construction of the trim strip along one edge of the lower sash, such strip being so arranged that it can be easily turned out into the room in order to make it possible to then swing the lower sash out into the room; the arrangement of such trim strip being such that it is normally locked in its working position and can only be unlocked therefrom when it is intended to swing the lower sash out into the room, such unlocking being then easily performed: to provide an improved form and construction of the parting strip which separates the two sash from each other along the side of the casing at which the upper sash swings out into the room; and in this connection to provide an improved arrangement for raising this parting strip when the inner or lower sash is to be raised in order to allow the outer or upper sash to be swung out into the room: to provide an arrangement in which the two sash are hinged along opposite edges and opposite sides of the casing, so that they swing into the room from said opposite sides and edges, the I lower sash being of greater vertical dimension than the upper sash so that a better construction is provided: and in other ways and manners to improve the construction of such devices and structures.

,Other objects and uses of the invention will appear from a detailed description of the same which consists in the features of construction and combinations of parts hereinafter described and claimed. 7 In the drawings: H

' ing having the'sides 20 and 2|, the top 22, and

The construction illustrated includes the casthe bottom or sill 23. The inner or lower sash is designated 24', and the outer or upper sash by the numeral 25. It will be noted that the :inner or lower sashis of greater Vertical dimension than the outer or upper sash. It will also be noted'that there is a head housing 26 above the position of the inner or lower sash so that when said sash is raised into the position of Figure 9 it can travel up into this head housing a 5 sufficient distance to permit the outer or upper sash to be swung out into the room when said sash is lowered into the position of Figure 9. This head house conveniently constitutes a sheet metal strip of U-shape located above a slot 10- through which the upper portion of the inner sash rises when at its extreme upper'limit of travel so that the slot 2! through which the inner sash then moves is protected and enclosed and foreign matter is prevented from gaining 5' access to the room.

The sides of the window casing are provided with the usual outside trim strips 28 and 29 at the two sides of the window, and the outer or upper sash travels against these strips. There 2 is also provided a fixed trip strip 30 along the side 2| of the casing and against the inner edge of the lower or inner sash. There is a trim strip 7 3| along the other side of the casing adjacent to.

the other edge of the inner or lower sash, but 25 this latter'trim strip is divided into upper and lower sections 32 and 33 as best shown in Figures 1, 9 and 10. The upper section 32 is permanently fixed, whereas the lower section 33 is hinged in the manner to be presently explained. 30

There is provided a pulley 34 in the upper portion of the side 20 of the casing, in line with the outer or upper sash, and a cord 35 extends from a suitable fixture on said sash'up and over said pulley and is connected to the counter-weight or 3 counterbalance 36 which Works in the side 20 of the casing; and there is provided a pulley 3'! in the'upper portion of the side 2| of the casing, in line with the inner or lower sash, and a cord 38 extends from a suitable fixture on said sash up 40 and over said pulley and is connected to the counter-weight or counterbalance 39 which works in the side 2| of the casing. In the arrangement herein disclosed the cords 35 and 38 are connected to the hinges whereby the sash are supported, but'manifestly other attaching fixtures may be used on occasion.

It will also be noted that due to the one-sided support of the inner or lower sash, at its right hand edge, there is a tendency for said sash to swing counter-clockwise when viewed as in Figure 1 so that its upper left hand corner tends to swing out and bind against the left hand side of the casing. Likewise, due to the one-sided support of the outer or upper sash, at its left hand edge, there is a tendency for said sash to swing clock-wise when viewed as in Figure 1 so that its upper right hand corner tends to swing out and bind against the'right hand side of the casing.

I have therefore provided the roller 40 which is I mounted in a recess 4| in the upper left hand side of the inner or lower sash 24 and travels against the face of the left hand side of the casing; and have provided a roller 42 which is mounted in a recess 43 in the upper right hand side of the outer or upper sash 25 and travelsagainst the face of the right hand side of the casing. These rollers ensure proper support for the respective sash, and also they very greatly ease the vertical'movements of the sash in the casing.

Referring to Figure 2 in particular, there is provided a permanent parting strip 44 between the twosash at the left hand side of the structure, said parting strip being fastened to the face of the left hand side 20 of the casing. This part ing strip extends the full height of the structure. There is an angle bar 45 fixed to the face of this parting strip, one arm of said angle bar being secured to the outside face of the parting strip and the other arm of the angle bar extending outwardly adjacent to the outside face of the parting strip, but separated therefrom a slight distance to establish a slot between the outside face of the parting strip and the inner face of said arm of the angle bar as will be apparent from examination of Figure 2 in particular. There is thus provided an outwardly extending flange of the angle bar reaching outwardly towards the left hand side of the casing. The outer or upper sash is provided with two hinges Q5 and 47 located in notches or recesses 48 and $9 in the left hand edge of said sash. Each of these hinges includes a plate 59 which is fixed to the edge of the sash, and a hinged plate 5! which is bent into the form of a hook and embraces the outwardly extending flange of the angle bar 45 as best shown in Figure 2. This arrangement is such that when the sash is raised and lowered in the usual window opening and closing operations the hinges are properly supported against tilting movement due to the weight of the sash, and when the outer or upper sash is swung out into the room into the position of Figure 9 said hinges are also able to resist the tendency of the sash to tilt out into the room. Furthermore this arrangement is such that the sash is readily set into place and will swing on hinges which pivot close to the left hand side of the casing.

Referring to Figures 3 and 8 in particular, the inner or lower sash is supported by the hinges 52 and 53 located in notches or recesses 54 and 55 in the right hand edge of the said sash. Each of these hinges includes the plate 55 which is secured to the edge of the sash, and the plate 51 which is bent into hook form as best shown in Figure 3. There is an angle bar 58 having one arm secured to the face of the trim strip 38 and its other arm extending outwardly towards the right hand side of the casing, but separated slightly from the edge of the trim strip as shown in Figure 3 so that there is provided a narrow outwardly facing slot between the arm of the angle bar and the trim strip. The plates 51 of the hinges are hooked over the outwardly extending arm of the angle bar so that said hinges are properly supported by the angle bar, but are permitted to slide up and down freely with movements of the inner or lower sash. This arrangement also is such that the sash is properly supported against tilting tendencies either when in its normal or working position, or when swung out into the room. Furthermore, this arrangement is such that the line of hinging action is brought close to the face of the sash itself.

It will be noted that when the inner or lower sash to he swung out into the room it is necessary to remove the trim strip 3| or a portion thereof from the edge of the sash 24. For this purpose said trim strip is divided into the upper and lower sections 32 and 33 previously referred to, and the upper section 32 is permanently attached to the left hand side of the casing, while the lower section of said trim strip 33 is so mounted that it can be swung out into the room or into position where it will not interfere with the outward swinging of the sash 24. Referring especially to Figures 2, 4, 9, 19, 11 and 12, the upper and lower ends of the lower trim strip section it are provided with the hinge plates 59 and 66 which are of the form shown in Figure 12. These extend outwards beyond the edge of the trim strip itself and are slotted as shown at 6! (see Figure 12). There are provided the companion fixed hinge plates 62 and 63, and in the arrange ment shown the plate 62 is fixed to the lower end ofthe trim strip section 32, and the plate 63 is fixed to the sill 23 of the casing. These plates 62 and 63 also extend out substantially as far as the plates 59 and 60. Pins 64 are secured to the plates 62 and 63 and reach vertically into the slots 6| of the plates 59 and 83 respectively, so

that the hinge plates 59 and Bil are permitted to slide edgewise a distance limited by said slots. The arrangement is however, such that the sliding movement must be towards the sash, that is,

outwardly from the room, as when the trim strips are in alignment as shown in Figure 9 the pins 84 lie at the sash ends of the respective slots as shown in Figure 12. At such time also the outer edge portion of the trim strip section 33 lies within a recess or groove 65 formed along the edge of the inner or lower sash.

When the inner or lower sash is to be swung into the room it is first raised high enough to bring its lower edge slightly above the upper end of the trim strip section 33. This will release the said trim strip section from the sash. There are small plates 66 secured to the plates and $53 at the outer or overhanging ends thereof, and said plates 56 are provided with notches B? at their inner ends as shown in Figure 11. The plates 59 and G0 are provided with pins 68 in position to engage these notches when the trim strip sections are in alignment with each other so that at such times the lower trim strip section 33 is retained against turning or swinging movement with respect to the upper or fixed section 32.

It will now be evident that when the inner or lower sash has been raised suiiiciently, the trim strip section 33 may be moved outwardly sufficiently to release the pins 63 from the notches 637:, such movement being permitted by reason of the slots GI, and then said trim strip section may be turned or swung around until it lies face against the left hand side of the casing it, as shown by the dotted lines in Figure l, and then the sash may be lowered to bring its lower edge just above the surface of the window sill, and then said sash may be swung out into the room as shown by the position of Figure 8. During these operations the outer or upper sash is left in its raised position.

It may in some cases be found desirable to curve or round the edge of the inner or lower sash slightly as shown in Figure 2 to better clear the trim strip when the latter has been turned out into the dotted line position of Figure l.

There is provided a parting strip between of the sash at the right hand side of the casing. This parting strip includes a channel section 69 which normally stands in a lowered position as shown in Figure 8, and is of a height to lie against the outer edge of the inner or lower sash at such time. This channel section has the edges of its flanges inturned towards each other as shown in Figure 3, and there is provided a T-section which has its central web secured to the right hand side of the casing, and its cross member lying within the channel section as shown in Figures 3 and 6. This T-section extends the full height of the casing, so that the parting strip channel can slide up and down and he supported throughout its movements. The T-section does not reach outwardly from the side face of the casing far enough to interfere with the swinging movements of the outer or upper sash when the lowered, and in some cases it may be desirable to slightly round or curve" the edge of the sash for this purpose as shown in Figure 3.

It will be seen that when the outer or upper sash is to be swung out into the room the inner or lower? sash is raised, and then or at the same time the parting strip is to be raised. In order to insure raising of both the sash and the parting strip at one and the same time I have provided a clip on the top of the inner or lower sash. This clip includes a metal strip H having a finger piece '52 by means of which it can be movedback and forth. This clip is conveniently supported on a block '23 which extends upwardly from the top of the sash so that the clip can be set in or out with respect to the face of the sash. This clip is provided with a notch l l which receives the edge of the T-section when the clip is projected outwardly to engage the parting strip. The parting strip itself is provided with a notch 75 to receive the clip when the clip is projected, and then when the sash is raised the parting strip will rise with it. Thus, when the inner or lower sash is raised preparatory to lowering the 'outer or upper sash and swinging the same inwards, the parting strip at the right hand side of the casing is also raised so that thereafter the outer of upper sash can be swung out into the room.

I wish to call attention to the fact that I do not limit myself to arrangements in which the outer or upper sash is to be swung from hinges 10- cated at the left hand side of the casing, and in which the inner or lower sash is to be swung from hinges located at the right hand side of the casing, as rnanifestly'this arrangement might be reversed, but I intend to cover generally arrangements in which the hinging of the two are accomplished at the opposite sides of the casing.

I do not limit myself to the constructions herein illustrated and disclosed, but I intend to cover also other equivalent forms of construction.

I claim:
